How to pass a tuple down into python code?

[Andrea Aime]

Hi,

with with python code, I use "get" to fetch a tuple and get back a list of Objects.

However, when I try to set the tuple back into a variable in python code, at a later stage, using "set", the python

call using the set object fails:

"Cell suid must be a list or tuple. Got [N, 2]"

I'm guessing set created a list in python instead of a tuple? How do I force it do create a tuple instead?

Cheers

A Java List will become a PyJList in Python, which is just a wrapper around the Java object so that the list contents do not need to be copied until they are needed. PyJList is designed to be "duck typing" compatible with a python list. There is no way to have Jep directly perform any extra conversion in the set method, you will have to add logic in Python to perform any extra conversion. Since PyJList is a sequence you can just use the builtin tuple function like this:

jep.set("a", list);
jep.exec("a = tuple(a)");
